Perturbation theory analysis of the strain-dependent superconducting phase diagram for SrRuO
John Deisz
Previously, it was shown that a superconducting state dominated by singlet intra-band pairs emerges from the fluctuation exchange approximation (FLEX) applied to a re…
Spin-orbit induced mixed-parity pairing in SrRuO: a quantum many-body calculation
J. J. Deisz, T. E. Kidd
The unusual superconducting state in SrRuO has long been viewed as being analogous to a superfluid state in liquid He. Nevertheless, calculations based on this odd-pari…
The superconducting phase diagram in a model for tetragonal and cubic systems with strong antiferromagnetic correlations
J. J. Deisz
We calculate the superconducting phase diagram as a function of temperature and z-axis anisotropy in a model for tetragonal and cubic systems having strong antiferromagnetic fluctu…
Single-Particle Excitations in a Two-Dimensional Strong-Coupling Superconductor
D. W. Hess, J. J. Deisz, J. W. Serene
We present calculations of the single-particle excitation spectrum for a 2D strong-coupling superconductor in a conserving approximation. Spectral weight at low frequency is substa…
